Anyone using stock LS clutch fan?

[chevydog66]

Will the stock LS fan fit in the original truck fan shroud? Or will the motor set too far back or forward? I am waiting on headers and oil pan in order to drop mine in. Hopefully in the next few days if Doug Thorley headers show up. Just wanting to know if I need to order a new rad/fan combo.

I am using one on my 5.3, along with the truck's original shroud and radiator, and with the adapter plates I used it sits the fan perfectly in the shroud.

Ah, yes I can see. Looks good!! And cheaper than buying a new rad/fan.

I got a set of electric fans for a LS1 F-body for $50. Fits the truck radiator just about perfect.

If you are using ECE mounting hardware, I highly doubt any sort of mechanical fan would fit:

I'm using the Entropy rad/fans and ECE mounts. It is the downside to the ECE setup, but I wanted an easy to install secure setup, so it is what it is!

woah....thats the ECE kit in the intended location? I guess I'll have to get some of those offset plates then. I'm running e-fans, but wanted the motor farther back for performance reasons. 2" from the looks of that pic...though I do want to leave enough room to hide the coil packs on the back of the motor so it'll have to be far enough out for that.

Yep, that's it --

What's the offset plate? You making them yourself?

Every time I look at it, I think about how much I'd like it back about 3-4"

It looks like the fan might go on, but be real close to the rad. very efficient cooling.

I would if I had the stuff to fab them up with. I've seen others that looked similar. I even seem to remember Moroso making some? Here's a pic and link:

The position of the middle plate is where mine is.

If I would have been thinking about it from the start, I would have welded 3" of steel to the back of the upper mounting plate, drilled 2 more holes in it, and used them that way.

Not impossible for me to do at this point, but I'm not sure I have the urge to jack everything up and un-do it.

I think they'd be about perfect if you used the back holes in the front of the block, and had that extra 3" or whatever in the back.

I got it in and here is what it looks like, about 1 1/8". Thinking I might have to cut the bottom out of the shroud and slide it over the top. I will try to figure it out tomorrow.
